Warm Up 1/27/14 Voices are at “0” Evaluate our Learning Target for today. • Where do we obtain energy? In other words, what are our sources for energy? • How do we transform energy? In other words, what form does it need to be in for us to be able to use it?

History of Wind Energy, Types of Turbines, and Applications of Wind Energy
“Windmills have fascinated us for centuries and will continue to do so. Like campfires or falling water, they’re mesmerizing; indeed, entrancing.” Paul Gipe, Wind Power for Home, Farm, & Business
Wind Energy has been Popular for a long time The pilgrims arrived under the power of wind. Cape Cod was home to the first windmill in America. Wind helped fuel our country’s early economy.
Dutch Style Windmills used for 100s of years across the World
Early Electric Wind Turbines helped Electrify Remote Farms in the early 1900’s
Birth of the Modern Wind Turbine California Wind Turbines 1980’s Smith-Putnam 1.25 MW Turbine Vermont, 1940's
Types of Electricity Generating Windmills • Small (10 kW) • Homes • Farms • Remote Applications • (e.g. water pumping, telecom sites, icemaking) • Intermediate • (10-250 kW) • Village Power • Hybrid Systems • Distributed Power • Large (250 kW - 2+MW) • Central Station Wind Farms • Distributed Power KidWind Project | www.kidwind.org

Wind Turbine Applications • Generating electricity at Remote Sites • Producing electricity in parallel with utility • Water Pumping
Drivers for Wind Power • Rising Fuel Price and Uncertainty • Declining Wind Costs • Federal and State Policies & Incentives • Local Economic Development • Environmental Stewardship • Energy Security • Consumer Demand

Some Concerns about Wind(that can be addressed with proper information) • Visual / Aesthetic • Property Values • Noise • Birds • Safety • Are benefits real?
Are the benefits real? • Back up Power? • Turbines do not require any new back up generation or spinning reserves. • Emission reductions? • Wind energy is accepted on the grid before any other source when it is available, offsetting the need for more polluting sources. Each MWh of wind is one less MWh of electricity from a fossil fuel plant • Economics? • Wind provides long-term price stability and is competitive with today’s energy costs. Economic benefit is realized by whoever buys (and sells) the power.
